TVS - Diodes

TVS (Transient Voltage Suppression) diodes are electronic components that help protect circuits against voltages spikes, which are short-term periods of abnormally high voltages exceeding normal operating voltage levels. These components offer protection to electrical circuits by blocking, redirecting, and limiting undesired electrical transients that damage sensitive electronic components.

A5KP54A-G is a unidirectional TVS diode designed to protect equipment from overvoltage transients. It’s designed with Glass Passivated Junction Technology and features Dual-Voltage suppression zones making it suitable for general purpose and automotive applications. The diode is RoHS and WEEE compliant and can be used across a wide range of temperatures.

A5KP54A-G is a fast acting TVS diode capable of protecting components from transients with peak pulse power of 5000W and working voltage of 18V. The device has a maximum clamping voltage of 44V and stand-off voltage of 28V. It is constructed with a 63V breakover voltage and withstands repetitive peak reverse voltages of up to 63V. Its breakdown current ranges from 5.0A to 10.0A.

The working principle of the A5KP54A-G relies on the zener breakdown. It works by allowing a controlled amount of current to flow safely through it and, simultaneously, reducing the voltage to a safe operating voltage level. As soon as the voltage exceeds the rated breakdown voltage, the diode enters the avalanche breakdown region. This forces the diode to act as a current limiter and helps dissipate the excess energy through the diode in the form of heat. Then, the diode rapidly clamps the voltage to a safe level.

The A5KP54A-G is ideal for protecting low power circuits. It can be used in general purpose applications such as 12V and 24V automotive power lines, machine and appliance control boards, and low-power telecommunications systems. It also provides line protection for audio/video equipment, USB-based power converters, and high-definition TV.

In addition, the A5KP54A-G is capable of providing excellent ESD protection to any circuit. Since it has a low capacitance of 1.6pF and low leakage current of 2μA, the diode is ideal for protecting sensitive digital systems. It can also be used as an ESD device in conjunction with the ESD protection switch.

The A5KP54A-G TVS diode is a fast and safe to use device. It can help protect circuits from voltage spikes and provide excellent ESD protection. It also has a low-leakage current and capacitance, which makes it a great choice for low-power applications.
